An interdisciplinary team of scientists has identified a new mobile DNA element in the Wolbachia parasite, which may contribute to improved control strategies for mosquito vectors of diseases such as Dengue and West Nile virus.

It is well known that psychiatric stress is associated with accelerated aging. Now, a new study shows that a gene mutation interacts with multiple types of psychiatric stress including post-traumatic stress disorder (PTSD), pain and sleep disturbances in association with cellular aging.

A study reveals new insights into how cells respond to oxygen deprivation. The researchers found that chromatin, the complex of DNA and proteins where all genes reside, quickly changes in response to low oxygen.

Research highlights role of immunological imprinting -- or how the immune system fights the flu after previous exposure to the virus via infections or vaccinations -- in the elicitation of new antibodies.

An active substance that has been known for 30 years could unexpectedly turn into a ray of hope against eye tumors. This is shown by a new study. The plant leaves of which contain the tested substance is anything but rare: At Christmas time you can find it in every well-assorted garden center.

As an organism grows and responds to its environment, genes in its cells are constantly turning on and off, with different patterns of gene expression in different cells. But can changes in gene expression be passed on from parents to their children and subsequent generations? Researchers have now demonstrated that epigenetic information carried by parental sperm chromosomes can cause changes in gene expression and development in the offspring.

In favorable conditions, many bacteria propel themselves to food sources and other sites of interest using whip-like molecular propellers known as flagella. However, according to new research, members of the bacterial class Gammaproteobacteria eject their flagella when nutrients are scarce.

Androgens stimulate prostate cancer cells to grow. Many drugs to target that cancer focus on stopping androgen biosynthesis or blocking the androgen receptor, or AR. Researchers have discovered a new function of the AR in prostate cells -- the AR is imported into and localizes to mitochondria of the cell, where it plays a novel role in regulating multiple mitochondrial processes.
